Waterjet Cutting Overview
Waterjet Cutting is a method of cutting materials using a jet of water. This can
be done utilizing water only for soft/less dense materials such as foam or by adding
to the waterjet for cutting hard/dense materials such as tool steel. The water is
forced through a precision orifice, or jewel, to create a well defined stream of
water. This stream of water is typically produced under pressures of 40,000 to 60,000
PSI (pounds per square inch). For comparison, the water pressure in your house is
about 60 PSI (pounds
per square inch).
History of Waterjet Cutting
Water Jet Cutting was first used by Dr. Norman Franz in the 1950's. Dr. Franz was
a forestry engineer who was looking for an easier way to cut lumber from large trees.
Though Dr. Franz never created a production lumber cutting machine, his experiments
helped Water Jet Cutting evolve into what it has become today.
Two decades later,
Dr. Mohamed Hashish found a way to add abrasives to the waterjet stream. This opened the door
to a whole new world of possiblities. With abrasives, a waterjet cutting machine
can cut through virtually any material.
